He builds tools that track and evaluate AI across engineering workflows. ## About Jack Fitzsimons helps engineering teams figure out if their AI tools actually work. As co-founder and CTO of Oblivious, he builds systems that track coding agents from the initial prompt to production. Instead of evaluating AI in a vacuum, his work relies on real-world developer signals like failed CI runs and stalled pull requests. Before Oblivious, Jack worked on computer vision at NASA's Jet Propulsion Lab and analyzed data at ElectroRoute. He holds a DPhil from Oxford and contributes to the UN's Privacy-Preserving Technologies Task Team. Based in Dublin. ## Upcoming Sessions ### Conference India 2026 ยท November 25, 2026 Bengaluru, India - [The PR Is the Eval](https://www.wearedevelopers.com/events/conference-india-2026/sessions/2012-the-pr-is-the-eval) ## Links - [LinkedIn](https://www.linkedin.com/in/jack-f-300810122/)
